Laser Beam Testing

Introduction

COMPLETE LASER BEAM ANALYSIS | High resolution wavefront measurement

Based on a patented technology, Phasics wavefront sensor simultaneously provides both phase and intensity maps of unrivalled high resolution. It combines to the SID4 software to deliver a complete diagnostic of the laser beam: wavefront aberrations, laser beam parameters, beam profiles, M2 beam quality parameter… It is compact and it easily positions at any point of the laser chain as it directly measures diverging beam.

Introduction

Phasics technology – “Quadriwave lateral shearing interferometry”- delivers the phase and intensity of an incident laser beam. Beam parameters including M2 and aberrations are calculated from this one shot acquisition.

Phasics technology stands out for its very high spatial resolution and its ability to measure diverging beam with no relay lens. Thus it provides very accurate outcomes and it is easy to integrate in any set-up.

Set Up

► Phasics solution for laser beam testing combines one of our high resolution wavefront sensor with the SID4 software package. This package manages acquisition and analysis of phase. Trigger is possible.

Phasics wavefront analyzer can be positionned at any point of the laser chain, whether the beam is collimated or diverging

Phase measurement of a segmented wave front using PISton and TILt interferometry (PISTIL)

New architectures for telescopes or powerful lasers require segmented wave front metrology. This paper deals with a new interferometric wave front sensing technique called PISTIL (PISton and TILt), able to recover both piston and tilts of segment beams. The main advantages of the PISTIL technique are the absence of a reference arm and an access to the tilt information.
